OpenWrt support for Xiaomi AX9000

@kylemd

Sorry if this has been solved elsewhere in the thread, I have searched but I couldn't find anything (other than regulatory stuff, which I've tried)...

I'm on latest (23.05.2) release and cannot get either of the 5ghz bands (radio1 or radio3) working @ 80mhz. I have set country to US and replaced board-2.bin and still devices fail to pick up the channels and connect.

I can successfully scan for other networks with those radios from luci (haven't tried joining though)

Does anybody have any suggestions as to where I could start looking to resolve the issue?

Might sound like a stupid question, but did you reboot the router after replacing the board-2.bin file?

Not sure about the 23.05.2 version but I'm on SNAPSHOT and this board file works. It's only for QCN9074 though and only radio3 antenna can be set to 160MHz, while radio1 can only run at 80MHz. Please see config from my router as reference:

The above would give you 2 Wi-Fi APs, one named WiFi which will be 2.4GHz/5GHz and one named WiFi-5G for 5GHz and this one will also be on 160MHz bandwidth. The other antenna (radio1) can only do 80MHz.

This can be easily edited either through an SSH session with vim or using WinSCP to connect to the router (it has built-in text editor).

If you make changes to these files and replace the board-2.bin file, you will need to reboot your router else you can get errors instead.

One other thing is that it can take up to 10 minutes for the Wi-Fi network to show up (usually takes no more than 1 minute) due to the antennas needing to scan for DFS channels. Hope this helps.
